Terrafugia CEO Responds To "Flying Car" Criticism

waderoush writes "The majority of the comments on last week's Slashdot post It's Not a Flying Car — It's A Drivable Airplane were critical, even dismissive, of Terrafugia's work to build a two-passenger airplane with folding wings that's also certified for highway driving. We boiled down these criticisms to the dozen most commonly expressed points, and today we've published responses from Terrafugia CEO Carl Dietrich. While hybrid airplane-automobiles are an old (some would say laughable) idea, Dietrich argues that current materials and avionics technologies finally make the concept feasible."

    I was thinking about this a couple of nights ago, and the only thing that came up to me was the following:

    1. A "drivable airplane" makes sense. In the way that you do not have to pay for hangar space and keep it safe and cozy at home. You just store it at home. You just "drive" the vehicle to the airport, put it together, do your pre-check inspection, fly, do your post-check inspection, fold, drive to destination. It's not the "Jetson's" concept, you have to be a licensed pilot, but it's, in a sense, practical enough for use.

    2. Terrfugia's CEO state that the materials are not available to make it practical. I certainly hope so. Folding, flying, driving it's going to put a lot of stress to a lot of parts on the vehicle. Flying or driving is bad enough to cause problems to components, combining both in one vehicle it's going to make matters worst. I sincerely wish them luck.

      A "drivable airplane" makes sense.
      I'm not entirely sure I agree (and yes, I am a pilot). In town, the drag of a car isn't a real big issue; at speeds of less than 30MPH, wind resistance is pretty minimal. At highway speeds of ~60MPH you've quadrupled the drag, and at typical general aviation aircraft speeds of 120MPH, you have 16 times more drag for a given shape and area than at commuter speeds. Consequently, a six foot wide car in town doesn't matter; at flight speeds, the drag of a six foot wide vehicle is pretty significant. That's why the Cessna 152 (a small trainer) is only something like 39 inches wide -- the narrower the fuselage, the less drag. A Cessna 172, a step up from the 152, is only about three inches wider than a 152, and most light single engine airplanes don't get *much* wider than that (I don't recall off-hand how wide a Cessna 206 or 207 -- the biggest single-engine piston airplanes Cessna makes -- are).

      What does this have to do with how much sense a drivable airplane makes? Well, the drawings of Terrafugia's design show a vehicle with a cross-section much like a car. It's rather wide, presumably for road stability and passenger comfort. Unfortunately, this makes a poor aircraft design because of the much greater speeds at which even a light sport airplane flies. Terrafugia is claiming some pretty impressive fuel economy numbers for their car, but I'm skeptical. I own a two-place tandem airplane (http://www.gecko-ak.org/N600LW/); it's about as skinny as an airplane can get, meaning its flat-plate area is pretty minimal, and therefore it's drag should be pretty minimal as well. I burn about 4.5 gallons per hour at 60 MPH. That works out to 13 miles per gallon -- better than my Nissan Frontier, but not by much. I sincerely doubt Terrafugia will get 26-27 mpg, as they claim, in a wider vehicle, at twice the speed of my airplane.

      I'm a pilot as well, if that somehow qualifies one to speak in this discussion. Anyway, you seem hung up specifically on mileage / air resistance. So let me point out a few things:

      1) A Cessna 152 (a 30+ year old plane) burns ~6 GPH at 111 knots (Vno), which is about double the fuel mileage of your plane and is quite in line with Terrafugia's numbers. It would seem that your plane just gets poor mileage.

      2) Yes, air resistance is exponential, it's relative to the square of the speed - your math is correct. But drag at 30 mph is VERY low, so just saying "16 times that" doesn't mean much. Secondly, to get actual drag you also need to consider drag coefficient and frontal surface area. Frontal surface area is two dimensions - you seem only focused on narrowness. The plane in the article is wide - but it's also a lower profile than "normal" planes. We'd have to have more specific dimensions to know if the overall frontal surface area is more or less than an equivalent plane. Third, as I mentioned above the drag coefficient comes into play. Aerodynamics have come a long way since Cessna's were designed and since your Falcon was designed (20+ years). If you can sufficiently reduce the coefficient, you can increase surface area and end up with the same amount of drag or even less.

      I'm an aeronautical engineer and I've done a fair amount of work on light sport aircraft designs. Because of the 120 kt speed limit, light sport aircraft never get going fast enough for parasitic drag to take strong effect. You're also neglecting the most important source of drag at low speeds, induced drag. Because of the ratios of induced drag to parasitic drag, the overall drag of the aircraft would most likely decrease the faster you go. It's a strange concept to work your head around, but the end result is that parasitic drag is so low I really doubt they're losing much at all with the wider body.

      As far as the fuel economy goes, light sport aircraft are quite fuel efficient. It wouldn't be unreasonable to expect around 6 gph at 120 knots. That results in about 23 miles (statute) per gallon. Better than my truck, and I'm sure that mileage could be improved upon.

      I'd reinforce your point #1 with the Rutan Long EZ which does 160 Knots (184 MPH) at about 5.1 GPH, for an astonishing 36 MPG at just shy of 200 miles per hour - even my trusty, highly reliable, and economical Saturn SL2 only gets about 30 MPG on the freeway! (at 80 MPH) And, unlike the 152, which is based on technology first developed in the mid 1950s, the Long EZ owes its legacy back to the early 1970s.

      (Yes, you read that right - the C152 airframe was only minimally changed in 1977 as a tweak of the previous, highly successful 150)

      It strikes me as quite appropriate that 21st Century technology would provide a significant improvement in capability/price/performance, when developed by current, high-quality engineers.

      BTW, Burt Rutan is a legend in the field. You might know his company Scaled Composites which won the Ansari X-Prize. He's a legend in the field. Not only did he build an experimental aircraft design that outperformed other designs by a factor of 2 or more in speed, while halving fuel burn, he did so with a design that's relatively cheap and easy to build.

      Some people like Rutan and Al Mooney just seem to "get it right" when it comes to aircraft design, and they do it over, and over, and over again. The Mooney Mark 20 is a line of high performance, high reliability, cheap, complex aircraft that provide solid performance, excellent safety and great economy. The Mooney Mark-20 line (there have been lots culminating in the current "Ovation") is one of the few GA single-engine airplanes with a proper "crash cage" resulting in excellent safety numbers - you are half as likely to die (per mile of flight) while flying a Mooney in IFR conditions than the industry average.

      A good indicator of airplane efficiency is its glide ratio - how far it moves forward for every foot dropped without power. The first number is the distance you move forward, the second number is is how far you drop. It's a ratio, and the higher the first number relative to the second, the better. A Mooney has a glide ratio of about 13:1, while a Cessna does about 7:1. A long EZ or a VariEZE can do anywhere from 15:1 to 20:1, a Boeing 767 did about 12:1 in the famous Gimli Glider incident. Many ultralights do as badly as 3:1.

      Can they do it? I'm quite sure they can. As soon as I can afford one, I'll probably buy. (It'll take me a few years, which is fine, since they won't be ready and tested by the "early adopters" for a few years, anyway)

      2) Reliability. If your car engine dies, you can simply pull off to the side of the road. Obviously, you can't do this in an aircraft. This reliability is often achieved by redundancy. A simple example if this is spark plugs. Aircraft engines have two spark plugs per cylinder. If one dies, you will get reduced power, but it will be sufficient power to keep the aircraft in the air long enough to land safely. Now add the cost of duplicating major important aircraft components.
      3) Liability. This is probably the biggest reason there are no cheap aircraft. If something goes wrong and there is a crash, just about any company that built a part that is on that aircraft will be sued. Combine that with many juries anti-corporation mindset and you've got a huge problem.

      Here's an example of #3. Let's say you want to take video of what it's like to drive your prized 1960 Ford Fairlane, so you rig up this huge video camera mount on the steering wheel of your car. Next, you are feuding with you neighbor and as he sees you pulling out of your garage with the video camera on the steering wheel, he parks his F-550 pickup truck across the end of your driveway to prevent you from leaving. Your car is rather old, so it's not required to have seatbelts and doesn't. You speed out of your garage, down the driveway, and hit your neighbor's F-550 with your car. This causes you to fly forward and hit your head on the video camera and mount you have attached to the steering wheel, causing serious injuries.

      2) Your neighbor for parking his F-550 across your driveway in an attempt to keep you from leaving.
      3) Ford for making an unsafe automobile.

      If your wife chooses #3, what do you think are the chances of her being successful in suing Ford?

      Change the 1960 Ford Fairlane to a 1940's Piper Cub, the F-550 to a fuel truck, and the driveway to a runway and you have exactly what happened. To make things even more bizarre, the jury found the aircraft maker, Piper, liable for millions of dollars of damages for producing an unsafe aircraft design.

    1. Solution #1 - switch to an alternate form of energy. There are a ton of options. The last time I checked the sun was still shining and we can still get power from it. Be it solar, wind, or nuclear, there are a ton of options. Why don't we do this? Because the economics don't say we should. Oil is still cheap, but The *second* oil becomes too expensive, there will be a ton of alternate energy sources available to tap. The only reason we don't do it is becuase oil is STILL too cheap.

    2. We can also *gasp* change the way we live. Shit, I know i waste plenty of energy. Heating air conditioning... hot water in the mornings, driving to work, pure wastage. How can I get away with wasting energy? Simple, it's cheap. it's less than 5% of my total income so I don't give a crap. I pay roughly 6x that on mortgage. Before the world falls apart, I'm sure we can adjust the way we live at least a tiny bit. But OMG, you may have to sell you SUV and buy a geo metro. Truely the end of the world.

Perhaps you're thinking of Ethonal. Either way, source please.

    The mortgage crisis.. I guess I don't give a shit. There aren't any losers here. You have gready companies who sold a lot of mortgages when times were good never considering that things may turn south because that might impact their current earnings portfolio. If some of them go belly up its no big shakes to me. I frankly think a few of them SHOULD be put out of business becuase if there was anyone in this mess who was at fault, it was them.

    Then you have greedy homeowners who took crazy ass loans or "no paperwork required" loans. Look, buying a house is easily the single biggest investment of your life. If you don't run a few numbers through excel and say "does this make sense" then I don't really feel a lot of pity for you when you can't afford your house. It most likely means you overbought when you got the house (which most people do). But now you've lost your gamble so you have to declare bankruptcy and have to wait 7 years before you buy another house. It's not the end of the world.

    Fusion: I won't even dignify this with more than "you're wrong."

    In other words, even if you live in a major city, public transportation will probably fail you in the US.

    This, however, is the result of deliberate actions taken on the part of the automotive companies; they bought bus and trolley lines and shut them down, and they lobbied for rail subsidies to be terminated in favor of the federal highway system. The federal government readily agreed, since it provided them with just one more form of leverage to apply against the states in their battle to severely curtail states' rights. Their attempts have been largely successful; for example, several states long avoided legalizing medical marijuana under the threat of their federal highway funds being terminated. This is all logical from the federal government's point of view, since marijuana was originally made illegal under the much-abused interstate commerce clause of the constitution, and that's the purpose of the highway system during peacetime.

    Anyway, that's a slight digression, but if you can even afford to live in a city (I paid $800 for a ROOM in San Francisco, my landlord who was the manager of a toys R us turned out to be a tweaker... fun shit.) it doesn't necessarily follow that public transportation will do you any good.

How brilliant can this hidden legislation be if it can't even get a simple majority in the house they run to consider voting for it? Ah... perhaps that's because it doesn't exist, and the GP was blowing hot air out of ignorance about how such things work, and you're really stretching it to give him some cover. It's just silly.

    Google is your friend. Just look up "solar cell energy to manufacture", and you will get 588,000 hits about this, and plenty of sources showing that the life to make up for a solar cell's cost (in perfect weather and conditions) is far greater than the usable life of the cell itself.

    First, either you are lying or you are talking about the monetary cost of a solar system. It can take 10-30 years to pay off THAT cost, but that has nothing to do with the actual cost of producing the panel, and everything to do with supply and demand and artificially inflated prices.

    You have to keep in mind that right now what we're doing with our national effort is making war. Far from being profitable (unless somehow it drives the price of petroleum in the proper direction to dramatically increase the value of the dollar - kind of doubt that one) this is actually putting us into huge debt. If we simply put that effort into producing PV solar, and instead of turning it into a pork processing system :) we just did everything at-cost, we could do this shit tomorrow. Or at least get started.

    As the AC sibling comment to this one says, the very first hit on your search terms is Can Solar Cells Ever Recapture the Energy Invested in their Manufacture? and the answer is yes:

    The 1983 book by Hu and White [1 ] summarises the results from a 1977 Solarex study [ 2] which found an energy payback time of 6.4 years for the manufacture of solar modules using silicon cells of 12.5 per cent efficiency. In other words, these modules would need to operate for that time in order to produce as much energy as was invested in steps such as the reduction and refinement of the silicon, crystal growth, cell production and module construction. Hagedorn [ 3] presented in 1989 a study of the energy costs for photovoltaic power stations (including grid connection) of monocrystalline silicon (such as are made by BP Solar in Australia), polycrystalline silicon (such as are made by Solarex in Australia) and amorphous silicon solar cells.

    So in other words, they knew in 1977 (the linked short-paper was written twenty years later) that even at then-current (no pun intended) levels of efficiency that payoff was in under seven years. Today, with thin film panels, that should be substantially less.

    If we promoted solar more, and produced more of it, then the prices would go down (if everyone and their mother made a grid-tie inverter it wouldn't cost you so damned much, for example) and then the economic payoff for the end user would come much sooner. Until then, solar is pretty much for the wealthy and those living off-grid.

    Actually, they do. Every single elected offical in Washington cares deeply about their country

    What?

    This proves that you have no idea what you are talking about.

    People who care about this country are not starting illegal wars, driving up the national debt, getting rich in the process, and then taking the money out of the country and doing further harm to our economy.

    Are you paid to say this shit, or are you just brainwashed?

    The US is FAR from bankrupt. China's only where they are in the world because we're allowing them to grossly distort the currency exchange, because we want them to work for peanuts.

    The US's debt is truly astronomical. We're overdrawn on our credit as it is.

    Nuclear: Plans are on the tables, Greenpeace's founder is endorsing Nuclear... sorry, there will be new plants built or chartered by the next Presidential Election. Maybe before this one.

    Greenpeace's founder's opinion is not being echoed by Greenpeace. 9 out of 10 hippies I talk to (this is not scientific but I talk to a lot of hippies) just refuse to come around to the idea of nuclear with breeder reactors. Incidentally, if we don't use breeders then using nuclear is a HORRIBLE and TERRIBLE idea; we can gain a couple orders of magnitude in efficiency this way. With breeders, nuclear can be not just practical but also profitable without subsidies.

    Solar: Ok, in small batches, for small device use, in the northeast, a photovotalic cell takes more energy to create than it will produce in its lifetime.

    Who told you that? It COSTS MORE TO BUY than it will save you in its lifetime, but that is the result of market forces, not physics.

    Think about it for a second; a solar system pays you off monetarily in about 20 years (yes, it's a long time) even without any special energy credits. Are you really saying that the power company charges me more for power (and I'm just talking about base rates here) than the sum of the amount that they charge the people who make the panels plus the amount that those people charge me for costs plus their profit? Obviously it's not impossible, but it is also not true . It takes less than seven years at 12 percent, which is a pretty reasonable estimate of the actual efficiency output (who cleans their panels enough?) when your panels are supposed to be around 14 or 15%. And that was for crystalline PV, not thin film, which requires less energy expenditure. It wouldn't seem so at first because of the petroleum-based nature of the plastics involved, but it is so hugely energy intensive to produce pure silicon that it winds up being that way anyway. They also cost less to ship due to their mass being a small fraction of a completed PV panel.

    Wind: Wind blows everywhere, some places essentially constantly. Couple a wind farm with a flywheel, and you can produce pretty damn good power. Essentially anywhere in the United States. Not eveywhere, but hardly "rare" for any meaningful definitions of that word.

    Wind has real problems; it truly HAS been a problem for flocks of migratory birds, but that is a lesser issue to the fact that those wind turbines are not especially inexpensive to produce, they do make a lot of noise (we are slowly waking up to the effects of noise pollution) so you don't want one in your backyard, and they MUST be placed up in the air so that they get wind in most cases. This keeps small-scale wind from being broadly useful, although it IS useful in some places.

    Of course, when the conveyor shuts down, and the jet stream shuts down, the weather patterns we take for granted are pretty much all going to change...
